道路標識カナダ
51. 市街地境界
市街地境界は、道路交通上、市街地・都市区域が始まるまたは終わる境界です。地名標識や市街地標識で示され、都市速度制限、駐車規則など特別規則の開始・終了地点となることがあります。
交通上の市街地境界は自治体の行政境界と必ずしも一致しません。法的意味はその国の道路標識と交通規則によります。
What is a city limit?
A city limit marks the boundary of a city, town, village, locality or municipality. On roads, it is often indicated by a place-name or boundary sign.
Does a city-limit sign always mark a built-up area?
No. A city-limit or locality sign may simply identify a place or administrative boundary. A legally defined built-up area can use a different sign or definition.
Does passing a city-limit sign always change the speed limit?
No. In some countries a locality or boundary sign has consequences for traffic rules, while in others it mainly identifies the place. Drivers must follow the traffic signs and rules that apply in that country.
Is a city limit the same as a municipal boundary?
Not always. Some signs indicate an administrative municipal boundary, while others identify a city, town, village or locality without exactly following the municipality's legal boundary.
What is the difference between a city limit and a built-up area?
A city limit identifies the boundary of a named place or administrative area. A built-up area is a traffic-law concept that may affect rules such as default speed limits. The two boundaries can coincide, but they do not have to.
52. 通行止め
通行止めは、道路または道路区間が一時的または恒久的に一部・すべての交通へ利用できない状態です。工事、事故、洪水、イベント、構造損傷など安全上の理由で実施されます。
運転者は閉鎖標識とバリアに従い、指定された迂回路を利用します。標識で示される場合、許可車両、緊急車両、居住者、地域交通には例外があります。
What does road closed mean?
Road closed means that access to a road or section of road is prohibited or unavailable to the traffic covered by the closure.
Why can a road be closed?
Roads may be closed because of roadworks, accidents, flooding, dangerous conditions, public events or other temporary or permanent restrictions.
Can you drive past a road-closed sign?
Normally, no. You must obey the closure unless an exception specifically applies to you, such as authorised access or local traffic where indicated.
53. ナンバープレート
ナンバープレート(登録番号標または車両番号標)は、登録当局から車両へ割り当てられた固有の登録識別番号を表示するプレートです。車両登録、交通取締、税、保険、駐車管理などで車両を識別するために使われます。
外観、形式、取付位置、必要枚数は国や車種で異なります。必要なプレートを正しく取り付け、はっきり見え、読み取れる状態に保ち、紛失、盗難、破損、交換時には現地規則に従います。
What is a licence plate?
A licence plate is a plate displaying the registration identifier assigned to a vehicle. It allows authorities and other authorised systems to identify the vehicle's registration.
Is a licence plate the same as a registration plate?
Yes. Licence plate, registration plate and number plate are different terms commonly used for the plate displaying a vehicle's official registration number.
Does every vehicle need a licence plate?
Most motor vehicles used on public roads must display one or more registration plates, but requirements differ for motorcycles, trailers, agricultural vehicles and other special vehicle categories.
Do vehicles need both front and rear licence plates?
This depends on the country and vehicle type. Cars commonly require front and rear plates, while motorcycles and certain other vehicles may require only a rear plate.
Must a licence plate remain visible?
Yes. A required registration plate must normally remain clearly visible and readable. It should not be hidden by luggage, dirt, accessories or other objects.
Can you modify a licence plate?
Generally no. Changing the characters, colours, dimensions or appearance of an official plate may make it invalid or illegal. Plates and authorised reproductions must comply with local specifications.
What should you do if a licence plate is lost or stolen?
Follow the local reporting and replacement procedure. Many countries require the loss or theft to be reported to the police or vehicle-registration authority before a replacement plate can be issued.
Can you drive with a damaged licence plate?
A plate must remain legible and compliant with local requirements. If damage prevents it from being read or makes it invalid, it should be replaced according to the local registration procedure.
Can a licence plate be personalised?
Some countries allow motorists to request a personalised registration combination. The available characters, formats and prohibited combinations are determined by the registration authority.
Does a licence plate stay with the vehicle when it is sold?
This varies between countries. In some systems the plate remains with the vehicle, while in others it remains associated with the registered holder and may be retained or returned when the vehicle is sold.
54. 充電ステーション
充電ステーションは、電気自動車またはプラグインハイブリッド車のバッテリーを電源へ接続して充電できる1基以上の充電器を備えた場所です。公道沿い、駐車場、サービスエリア、私有地などに設置されます。

What is a charging station?
A charging station is a location where electric vehicles can be connected to an electricity supply to recharge their batteries. A station may contain one or several individual charging points.
Who can use an electric-vehicle charging station?
Charging stations are intended for vehicles that can be externally charged, such as battery-electric vehicles and plug-in hybrid vehicles. The exact vehicle categories permitted may be indicated by local signs or operator conditions.
Is a charging space an ordinary parking space?
Not necessarily. A space beside a charger may be reserved for electric vehicles or vehicles that are charging. Drivers must check the signs and markings before parking there.
Can a petrol or diesel vehicle park at a charging station?
Not where the parking space is officially reserved for electric vehicles. An ordinary parking space located near a charger may be different, so the applicable signs and markings determine who may park there.
Can an electric vehicle park at a charging point without charging?
This depends on the local traffic and parking rules. Many charging spaces require the vehicle to be connected to the charger, even if the vehicle itself is electric.
Do you have to pay to use a charging station?
Charging may be free or subject to payment. The price and payment method are determined by the charging operator, while separate parking charges may also apply.
Can a charging station have a maximum parking time?
Yes. Traffic signs, parking regulations or charging conditions may establish a maximum duration to encourage drivers to move their vehicles and make the charger available to others.
Must you move the vehicle when charging is finished?
Follow the local parking rules and charging conditions. Some locations require vehicles to leave after charging or impose additional fees or time limits when the charging session has ended.
Does using a charger override ordinary parking restrictions?
No. A charging station does not allow a driver to ignore no-parking rules, reserved spaces, time limits or other traffic regulations. The vehicle must still be legally parked.
Are all charging stations equally fast?
No. Charging stations can provide different charging powers. Some are intended for longer parking periods, while high-power chargers can recharge compatible vehicles much more quickly.
55. 歩行者
歩行者は、道路、街路、通路、公共空間を徒歩で移動する人です。現地法により、自転車、車いす、ベビーカーなどの小型器具を押している人も歩行者として扱われる場合があります。
通常、利用可能な歩道、歩行者通路、歩行者区域を使用します。適切な施設がない場所で道路を横断・歩行する場合は、横断規則、信号、その他の現地交通規則に従います。
What is a pedestrian?
A pedestrian is primarily a person travelling on foot. Local traffic laws may also treat people pushing bicycles, wheelchairs, prams or certain other devices as pedestrians.
Where should pedestrians normally walk?
Pedestrians should normally use pavements, sidewalks, footpaths or other areas provided for pedestrians. Where these are unavailable, local rules determine where pedestrians may walk on or beside the road.
Which side of the road should pedestrians walk on when there is no pavement?
This depends on the country's traffic rules. Many countries require or recommend pedestrians to face approaching traffic, but the exact rule varies.
Where should pedestrians cross a road?
Use a pedestrian crossing, traffic-light-controlled crossing or other designated crossing where required or reasonably available. Where crossing elsewhere is permitted, choose a location with good visibility and cross carefully.
Do pedestrians always have priority at a pedestrian crossing?
The exact priority rule varies between countries. Drivers are commonly required to give way to pedestrians using or entering designated crossings, but pedestrians must still obey traffic lights and avoid entering the road dangerously.
Must pedestrians obey traffic lights?
Yes. Where pedestrian signals are provided, pedestrians must follow their indications and should not enter the roadway while the signal prohibits crossing.
Is someone pushing a bicycle a pedestrian?
In many traffic systems, a person who dismounts and walks beside a bicycle is treated as a pedestrian. The precise legal classification depends on local law.
Can pedestrians use a cycle path?
This depends on the road layout and local rules. Pedestrians may sometimes use a cycle path when no suitable pedestrian facility is available, but they must not unnecessarily obstruct cyclists or other authorised users.
Do turning vehicles have to watch for pedestrians?
Yes. Drivers turning into another road must watch carefully for pedestrians crossing the road they are entering and give way where required by local traffic law.
What should pedestrians do before crossing a road?
Check carefully for approaching traffic from all relevant directions, make sure there is sufficient time and distance to cross safely, and continue to observe traffic while crossing.
56. バス
バスは、公共交通、スクール輸送、私的輸送などで多数の乗客を道路上で運ぶための自動車です。乗用車より乗車定員が多く、座席のみ、立席を含む、または両方の形式があります。
運転免許、乗車定員、速度、シートベルト、バスレーン、停留所、乗降などに特別規則が適用される場合があります。分類や規則は国によって異なるため、現地交通規則に従います。
What is a bus?
A bus is a motor vehicle designed to transport a relatively large number of passengers. It may be used for public transport, school transport, private services or other passenger transport.
What is the difference between a bus and a coach?
A bus is commonly designed for frequent passenger boarding and may allow standing passengers, while a coach is generally designed for longer journeys with passengers seated. Exact legal definitions vary between countries.
Do you need a special driving licence to drive a bus?
Yes. Driving a vehicle designed to carry more than a specified number of passengers normally requires a dedicated bus or passenger-vehicle driving licence.
Can passengers stand on a bus?
Only when the vehicle is designed and approved to carry standing passengers. Coaches and other vehicles designed exclusively for seated passengers must not be used beyond their approved passenger configuration.
Must bus passengers wear seat belts?
Where seat belts are provided and local law requires their use, passengers must wear them correctly. Urban buses designed for standing passengers may have seating positions or operating conditions that differ from coaches.
Can buses use bus lanes?
Yes, where permitted. Bus lanes are commonly reserved for public transport buses, although local signs may also allow taxis, bicycles or other specified vehicles to use them.
Do buses always have priority when leaving a bus stop?
No. Some countries require other drivers to give way to buses leaving designated stops, particularly in urban areas, while others apply the normal merging rules.
Should you take extra care near a stopped bus?
Yes. Passengers may be boarding, leaving or crossing the road near the bus. Reduce speed where necessary and watch carefully for pedestrians emerging from behind or in front of the vehicle.
Do buses have special speed limits?
They can. Some countries impose lower maximum speeds on buses than on passenger cars, particularly on high-speed roads. Different limits may apply to buses and coaches.
Can a bus use a motorway?
Yes, normally. Buses that satisfy the applicable construction and access requirements may use motorways, but they must obey any vehicle-specific speed limits, lane restrictions and other local rules.
57. 警察
警察は、法律の執行、公共安全、道路交通へ影響する状況の管理を担う公的機関です。交通では車両検査、交通取締、事故調査、交通整理、緊急対応などを行います。
道路利用者は警察官など権限を持つ交通整理員の適法な指示に従います。現地法により、警察の指示は一時的に信号、道路標識、通常の交通配置より優先する場合があります。
What is the role of police in road traffic?
Police help enforce traffic laws, manage traffic, investigate collisions and respond to dangerous situations. They may also carry out roadside checks and direct road users.
Must you obey a police officer directing traffic?
Yes. Lawful directions given by an authorised police officer must be followed. In many countries, those directions take precedence over traffic lights, road signs and normal priority rules.
What should you do if police signal you to stop?
Slow down, follow the officer's directions and stop at a safe location as instructed. Do not make sudden movements or continue driving unless directed to do so.
Can police direct you through a red traffic light?
Yes, where authorised by local law. A police officer controlling traffic may instruct road users to proceed even when a traffic light or sign would normally require them to stop.
Can police check your driving documents?
Yes. Police may require drivers to provide documents such as a driving licence, vehicle registration, identification or proof of insurance according to local law.
Can police carry out alcohol or drug checks?
Yes. Traffic police may conduct legally authorised alcohol and drug checks using procedures such as breath, saliva or other approved tests.
Can police temporarily close a road?
Yes. Roads or lanes may be temporarily closed or traffic diverted because of collisions, emergencies, investigations, public events or other safety concerns.
What should you do near police controlling an accident scene?
Reduce speed, remain alert and follow all directions. Do not enter a closed area or interfere with emergency personnel, and leave sufficient space for emergency vehicles.
What should you do when a police vehicle approaches with emergency signals?
Follow the local rules for priority vehicles. Drivers generally have to make sufficient space, give way and stop where necessary so that the emergency vehicle can pass safely.
Can police order a parked vehicle to be moved?
Yes, where local law permits it. Police or another authorised authority may require a vehicle to be moved when it obstructs traffic, creates danger or must be removed for operational reasons.
58. 救急車
救急車は、緊急医療の提供や患者輸送のため装備・使用される車両です。医療機器と訓練された職員を乗せ、搬送中に治療する場合があります。
緊急出動中は警光灯とサイレンを使用し、特別な優先権や一部交通規則の例外が認められる場合があります。他の道路利用者は現地規則に従い、十分な通路を空け、進行を妨げない必要があります。
What is an ambulance?
An ambulance is a specially equipped vehicle used to provide emergency medical assistance and transport sick or injured people.
When does an ambulance have priority?
This depends on the local traffic rules and warning signals being used. Ambulances responding to emergencies commonly use flashing lights and a siren to indicate that other road users must make way.
What should you do when an ambulance approaches?
Remain calm and make sufficient space for it to pass. Slow down or stop where necessary, but avoid sudden or dangerous manoeuvres.
Should you stop immediately when you hear an ambulance siren?
Not necessarily in your exact position. Move or stop in a way that creates a safe passage without blocking an intersection, pedestrian crossing or another part of the road needed by the ambulance.
Can an ambulance pass a red traffic light?
Emergency vehicles may be allowed to pass a red light during an urgent response under special legal conditions. The precise rules differ between countries, and the ambulance driver must still take appropriate precautions.
Can an ambulance exceed the speed limit?
Many countries permit emergency vehicles to depart from certain normal speed rules during an urgent mission, subject to safety requirements and national legislation.
Can an ambulance drive through a traffic queue?
Yes, when responding to an emergency and legally permitted to do so. Other road users should create space and keep emergency corridors or access routes clear where required.
Can you follow an ambulance through traffic?
You should not use the passage created for an ambulance as a way to bypass congestion. Maintain a safe distance and continue to obey the normal traffic rules.
Do ambulances always use their sirens?
No. The use of warning lights and sirens depends on the urgency of the mission and local regulations. An ambulance transporting a patient does not necessarily need to use emergency signals throughout the journey.
What should you do near a stationary ambulance?
Reduce speed and remain alert. Medical personnel, patients or other emergency workers may be entering the road, and the ambulance may need to move unexpectedly.
59. タクシー
タクシーは、料金を受け取って乗客を希望地点間で輸送する車両です。タクシー乗り場から乗車、路上で乗車、電話やアプリで予約する方式などがあります。
通常、専用表示、屋根灯、特別ナンバー、地域許可などで識別されます。免許、運賃、営業規則は国や都市によって異なります。
What is a taxi?
A taxi is a vehicle used to transport passengers for payment, normally providing journeys requested by individual customers.
Where can passengers find a taxi?
Depending on the local system, taxis may be available at taxi stands, airports, railway stations, on the street or through telephone and app-based booking services.
Are taxis regulated?
Yes. Taxi services are generally subject to licensing and operating requirements, although the exact rules concerning vehicles, drivers, fares and permitted operating areas vary between jurisdictions.
60. 車間距離不保持
車間距離不保持は、前車が急減速・停止した場合に安全に反応・停止できる十分な距離を残さず接近して走ることです。安全な車間距離は速度、路面、天候、視界などで変わります。
運転者は前車との十分な間隔を保ち、雨、雪、霧など停止距離が増える条件ではさらに距離を広げます。
What is tailgating?
Tailgating means following another vehicle too closely to maintain a safe stopping distance.
Why is tailgating dangerous?
Following too closely gives the driver less time and distance to react if the vehicle ahead brakes, slows down or encounters an unexpected hazard.
When should you increase your following distance?
You should increase the distance in conditions such as rain, snow, ice, fog, darkness or poor road surfaces and whenever visibility or tyre grip is reduced.
61. ポットホール
ポットホールは、摩耗、天候、水、反復荷重、舗装劣化などにより路面に生じる穴・窪みです。大きさ・深さはさまざまで、凍結、豪雨、反復交通で悪化することがあります。
操舵、制動、車両安定性へ影響し、タイヤ、ホイール、サスペンションを損傷することがあります。前方路面を確認し、速度を調整し、危険な急操作を避けます。
What is a pothole?
A pothole is a hole or depression that develops in a road surface when the pavement becomes damaged or deteriorates.
How do potholes form?
Potholes can develop through a combination of water, temperature changes, traffic loads and deterioration of the road material. Cracks can gradually expand until pieces of the surface break away.
Why are potholes dangerous?
A pothole can cause a vehicle to change direction suddenly, lose stability or suffer tyre, wheel or suspension damage. Deep potholes can present a particularly serious hazard at higher speeds.
What should you do when you see a pothole?
Reduce speed when necessary, maintain control of the vehicle and avoid abrupt steering or braking. Only move around the pothole when this can be done safely without endangering other road users.
Should you brake while driving through a pothole?
If possible, reduce your speed before reaching the pothole. Sudden heavy braking or steering while passing over a damaged surface can make the vehicle less stable.
Are potholes particularly dangerous for motorcycles?
Yes. A pothole can disturb the steering or balance of a motorcycle and may cause the rider to lose control.
Are potholes dangerous for cyclists?
Yes. Bicycle wheels can be strongly affected by deep holes or sharp edges, particularly when the cyclist has little time or space to avoid the hazard.
Can a pothole damage a car?
Yes. Severe impacts can damage tyres, wheel rims, suspension components, steering parts or wheel alignment.
Should you swerve suddenly to avoid a pothole?
No. A sudden evasive movement may create a greater danger by bringing the vehicle into conflict with cyclists, pedestrians, oncoming traffic or vehicles in another lane.
Can a warning sign indicate potholes ahead?
Yes. Depending on the country's traffic-sign system, an uneven-road or general-danger warning sign may be used where poor road conditions create a significant hazard.
62. 通路
通路は、主に歩行者向けの比較的狭い経路で、許可されている場合はその他の道路利用者や小型車両も利用できます。市街地、農村、公園、森林、道路間などに設けられ、舗装されている場合と未舗装の場合があります。
通路は必ずしも歩道や自転車道と同じではありません。利用できる道路利用者は、その法的区分、幅、交通標識、地域規則によって決まります。
What is a path?
A path is a relatively narrow route intended primarily for pedestrians and, where permitted, other road users or small vehicles.
Is a path the same as a footpath?
Not necessarily. A footpath is specifically intended for pedestrians, while a path may also permit cyclists or other users according to local rules.
Is a path the same as a cycle path?
No. A cycle path is specifically designated for bicycles and other permitted users. An ordinary path does not automatically have that legal status.
Can cyclists use a path?
This depends on the legal status, width and signs applying to the path. Some paths permit cyclists, while others are reserved for pedestrians or particular users.
Can motor vehicles use a path?
This depends on local law. Some paths prohibit motor vehicles entirely, while narrow vehicles may be permitted on other paths unless traffic signs restrict access.
Can a path be part of the public-road network?
Yes. A narrow path can legally form part of the public-road network even when it is unsuitable for ordinary cars.
Does a path need to be paved?
No. Paths can be paved, gravelled, compacted or unsurfaced depending on their location and purpose.
Can traffic signs restrict access to a path?
Yes. Signs can reserve a path for particular road users or prohibit certain vehicles, regardless of whether they could physically fit on it.
Who has priority when a path joins a larger road?
The applicable local priority rules determine who must give way. Special rules often apply when a minor path joins an ordinary road.
Can pedestrians and cyclists share a path?
Yes, where both are permitted. Faster users should adapt their speed and avoid endangering or unnecessarily obstructing pedestrians.
Can a path cross another road?
Yes. At the crossing, users must follow the applicable priority signs, traffic lights, road markings and general right-of-way rules.
Is every narrow route legally a path?
No. Its legal classification depends on the definitions and regulations of the country concerned. A narrow route might instead be a footpath, cycle path, private access road or another type of facility.
63. 粒子状物質
粒子状物質(particulate matter、PM)は、空気中に浮遊する微小な固体粒子または液滴です。道路交通では、排気ガス、ブレーキ摩耗、タイヤ摩耗、路面摩耗のほか、通過車両が巻き上げるほこりからも発生します。
粒子状物質は一般に粒径で分類されます。PM10は直径およそ10マイクロメートル以下、PM2.5はおよそ2.5マイクロメートル以下のより細かい粒子を指します。車両排出ガス基準、粒子フィルター、大気質対策などにより、これらの汚染物質への曝露低減が図られます。
What are particulates?
Particulates, or particulate matter, are very small solid particles or liquid droplets suspended in the air.
What are PM10 and PM2.5?
PM10 refers to particles with a diameter of up to approximately 10 micrometres. PM2.5 refers to finer particles with a diameter of up to approximately 2.5 micrometres.
Where do traffic particulates come from?
Road traffic can produce particles through engine exhaust, brake wear, tyre wear and road-surface wear. Passing traffic can also resuspend dust already present on the road.
Are diesel vehicles a source of particulates?
Yes. Combustion in diesel engines can produce very small soot particles. Modern diesel vehicles commonly use particulate filters to capture a large proportion of these exhaust particles.
What is a particulate filter?
A particulate filter is an exhaust-treatment device designed to trap particulate matter produced by an engine. Diesel particulate filters are commonly known as DPFs.
Do petrol engines produce particulates?
Yes. Petrol engines can also produce particulate emissions, particularly certain direct-injection engines. Appropriate emission-control systems may therefore include particulate filters.
Do electric vehicles produce particulates?
Fully electric vehicles produce no exhaust particulates from a combustion engine, but particles can still result from tyre wear, road wear and braking.
Are brake and tyre particles regulated?
Vehicle-emission regulation is increasingly addressing non-exhaust emissions. The European Euro 7 framework includes requirements concerning brake-particle emissions and tyre abrasion.
Is particulate matter the same as CO2?
No. Particulate matter consists of tiny airborne particles, while carbon dioxide is a gas. They are different types of vehicle emissions and are regulated for different environmental reasons.
How can vehicle particulate emissions be reduced?
Measures include effective particulate filters, cleaner vehicle technologies, correctly maintained emission-control systems and reductions in brake, tyre and road-wear emissions.
64. 大気汚染
大気汚染は、人の健康、環境、生態系へ悪影響を与える濃度で、気体、粒子、その他の物質が空気中に存在する状態です。道路交通は排気ガスに加え、ブレーキ摩耗、タイヤ摩耗、道路粉じんなど非排気由来の排出によっても大気汚染へ寄与します。
交通に関連する主な汚染物質には、窒素酸化物、粒子状物質、一酸化炭素、揮発性有機化合物があります。車両から直接排出されるものもあれば、大気中の化学反応で生成されるものもあります。車両排出ガス基準、よりクリーンな技術、交通管理対策などが排出削減に使われます。
What is air pollution?
Air pollution is contamination of the air by gases, particles or other substances that can adversely affect human health, the environment or ecosystems.
How does road traffic cause air pollution?
Vehicles produce pollutants through fuel combustion, exhaust systems, brake wear, tyre wear and road-surface interaction. Moving traffic can also resuspend dust already present on the road.
Which air pollutants are associated with road traffic?
Important traffic-related pollutants include nitrogen oxides, particulate matter, carbon monoxide and volatile organic compounds. Their relative importance depends on the vehicle, fuel and driving conditions.
What is nitrogen dioxide?
Nitrogen dioxide (NO2) is an air pollutant associated particularly with combustion processes and road traffic. High concentrations are commonly found near busy roads and densely trafficked urban areas.
What is particulate matter?
Particulate matter consists of tiny solid particles or liquid droplets suspended in the air. Road traffic can produce particles from exhaust, brakes, tyres and road surfaces.
Is CO2 the same as ordinary air pollution?
No. Carbon dioxide is primarily regulated as a greenhouse gas because of its contribution to climate change. Local air-quality pollution generally focuses on substances such as nitrogen dioxide, particulate matter, ozone and other pollutants that directly affect air quality and health.
Do electric vehicles cause air pollution?
Fully electric vehicles produce no combustion-engine exhaust emissions while driving, but they can still contribute to non-exhaust particulate emissions through tyres, brakes and road wear.
Can air pollution be worse near busy roads?
Yes. Concentrations of traffic-related pollutants can be higher close to heavily trafficked roads because many emissions occur close to ground level and near where people live and travel.
What is a low-emission zone?
A low-emission zone is an area where access by more polluting vehicles is restricted in order to reduce traffic-related air pollution. Access criteria may depend on factors such as fuel type, vehicle category and emission standard.
How can traffic-related air pollution be reduced?
Measures include cleaner vehicles, stricter emission standards, effective emission-control equipment, low-emission zones, public transport, cycling and walking, as well as traffic-management measures that reduce unnecessary congestion and emissions.
65. ラッシュアワー
ラッシュアワーは、多くの人が通勤、通学、その他の定期的な移動を行うため、道路や公共交通網の需要が特に高くなる時間帯です。通常、平日の朝と夕方から夜にかけて発生します。
ラッシュ時には渋滞、低速走行、移動時間の増加、頻繁な停止が生じます。運転者は安全な車間距離を保ち、焦らず、交通状況の変化を予測し、臨時または動的な交通管理措置に従います。
What is rush hour?
Rush hour is a period when unusually large numbers of people travel at the same time, resulting in increased traffic and often congestion.
When does rush hour occur?
Rush hour commonly occurs during the morning and late afternoon or evening on working days, but the exact times vary according to the city, road and local travel patterns.
Does rush hour always last one hour?
No. The term does not mean that congestion lasts exactly one hour. In busy urban areas, peak traffic conditions may continue for several hours.
Why does traffic become congested during rush hour?
Congestion develops when traffic demand approaches or exceeds the available road capacity. Intersections, merging traffic, collisions, roadworks and weather can make the congestion worse.
Should you increase your following distance in rush-hour traffic?
Yes. Leave sufficient distance to react to sudden braking and frequent changes in traffic speed. Avoid following another vehicle too closely even when traffic is moving slowly.
Should you frequently change lanes during congestion?
Unnecessary lane changes can create additional conflicts and may not significantly reduce journey time. Choose an appropriate lane, observe surrounding traffic and change lane only when it can be done safely.
Can speed limits change during rush hour?
Yes. Roads equipped with variable traffic management may display lower speed limits during congestion. Drivers must follow the speed limit currently indicated.
What is a rush-hour lane?
A rush-hour lane is an additional traffic lane that can be opened during busy periods to increase road capacity. It may use a lane or shoulder that is closed to normal traffic at other times.
Can you use a rush-hour lane whenever traffic is congested?
No. Such a lane may only be used when traffic signals or signs indicate that it is open. Never assume that congestion alone permits its use.
How can you prepare for a journey during rush hour?
Check current traffic conditions and expected journey times, allow additional travel time and consider an alternative route, departure time or mode of transport where appropriate.
66. 交通法規
交通法規は、人々が公道をどのように利用するかを定める法律や交通規則の体系です。運転者、自転車利用者、歩行者、その他の道路利用者に適用され、優先、速度、追い越し、駐車、信号機、道路標識、路面標示などを扱います。
交通法規は国によって、場合によっては地域によって異なります。道路利用者は、母国の規則と異なる場合でも移動先で適用される規則を知り、従うことが求められます。
What is a road code?
A road code is the body of traffic rules and regulations governing how road users must behave on public roads.
What does a road code regulate?
A road code can regulate subjects such as priority, speed, overtaking, turning, parking, traffic signals, road signs and road markings, as well as the responsibilities of different road users.
Are road codes the same in every country?
No. Although many traffic rules and signs are similar internationally, each country establishes its own traffic legislation and may apply different rules, signs, speed limits and requirements.
67. 可逆車線
可逆車線は、交通需要が大きい方向へ容量を増やすため、時間帯などに応じて通行方向を変更できる車線です。特定の時間帯に一方向へ交通が集中し、別の時間帯には反対方向へ集中する道路で使われます。
可逆車線は通常、車線上部信号、信号機、標識、可動式バリアなどで制御されます。自分の方向への通行が許可されていることを信号で確認した場合だけ進入します。
What is a reversible lane?
A reversible lane is a lane that can carry traffic in different directions at different times, depending on the traffic-management system in operation.
How do you know whether a reversible lane is open?
Drivers should follow the lane-control signals, traffic lights and signs above or beside the lane. A lane must not be used when the applicable signal indicates that it is closed to traffic in that direction.
Why are reversible lanes used?
They allow road authorities to increase capacity in the busiest direction without permanently adding another traffic lane.
68. 道路側溝
道路側溝は、道路や街路の端に沿って設けられ、雨水を集めて排水口などへ流す細い水路です。通常、車道と縁石の間にあり、コンクリート、舗石、路面の一部などで形成されます。
道路側溝は主に排水設備であり、交通車線ではありません。水、破片、排水口、凹凸などがある場合があるため、道路利用者は側溝付近で注意します。
What is a street gutter?
A street gutter is a drainage channel along the edge of a road that collects rainwater and directs it toward drains or another drainage system.
Is a street gutter a traffic lane?
Normally, no. A gutter is primarily part of the road's drainage system and is not intended to function as a normal traffic lane.
Why should cyclists take care near street gutters?
Gutters may contain water, leaves, debris, drain covers or uneven surfaces, which can reduce grip or make cycling less stable.
69. カーゴバイク
カーゴバイクは、通常の自転車より多くの荷物、子ども、その他の大きな積載物を運ぶため設計された自転車です。前後のボックスや荷台、延長された後部キャリア、多輪構造などを備える場合があります。
人力のみの場合も、電動アシストを備える場合もあります。許容寸法、乗車定員、自転車道の利用、電動アシストの上限などは現地の交通・車両規則によります。
What is a cargo bike?
A cargo bike is a bicycle designed to carry goods, children or larger loads than a conventional bicycle.
What types of cargo bikes are there?
Common designs include two-wheel box bikes, three-wheel cargo bikes and longtail bicycles with an extended rear carrying area.
Can a cargo bike be electric?
Yes. Many cargo bikes use electric pedal assistance to make it easier to move heavier loads or travel longer distances.
Is an electric cargo bike still a bicycle?
It can be. If the electrical assistance remains within the applicable power and assistance-speed limits, the vehicle may remain legally classified as a bicycle. More powerful or faster models may belong to another category.
Can a cargo bike carry children?
Yes, when it is designed and equipped for passenger transport. Children should use the seats, restraints, foot protection or other safety equipment provided by the manufacturer and required by local law.
Can a cargo bike carry goods?
Yes. Transporting goods is one of its main purposes. Loads must be securely positioned and must not make the bicycle unstable, obstruct the rider's view or exceed applicable dimensional or weight limits.
Can a cargo bike use a cycle path?
This depends on its dimensions and legal classification. Ordinary-sized cargo bicycles generally follow bicycle rules, while unusually wide models may be excluded from certain cycle facilities.
Does a cargo bike need a driving licence?
Normally not when it remains legally classified as an ordinary bicycle or electrically assisted bicycle. Faster or more powerful vehicles may be subject to different licensing requirements.
Is a helmet compulsory on a cargo bike?
This depends on the country's bicycle rules and the vehicle's classification. A model legally classified as a faster motorised vehicle may have different helmet requirements from an ordinary cargo bicycle.
Should you ride differently when a cargo bike is heavily loaded?
Yes. Additional weight can affect acceleration, braking, steering and stability. Reduce speed where necessary, allow greater stopping distance and take particular care when turning.
Can a cargo bike tow a trailer?
Yes, where permitted. The bicycle, trailer and total load must comply with the applicable dimensional, mass, braking and passenger-transport requirements.
Why should drivers take care around cargo bikes?
Cargo bikes can be longer, wider and heavier than ordinary bicycles and may need additional space when turning or stopping. Drivers should leave sufficient passing distance and avoid cutting across their path.

What is a forestry vehicle?
A forestry vehicle is a vehicle designed or adapted for forestry work, such as pulling machinery, carrying equipment, transporting timber or working on forest land.
Is a forestry vehicle always a tractor?
No. Forestry vehicles can include tractors, specialised self-propelled machines, trailers and other equipment. Their legal classification depends on their design and use.
What is a forestry tractor?
A forestry tractor is a powered vehicle primarily designed to pull, push, carry or operate equipment or trailers used for forestry work.
Can forestry vehicles travel on public roads?
Yes, when legally permitted and properly equipped. Registration, insurance, lighting, dimensions, speed and driving-licence requirements may apply before a forestry vehicle can use public roads.
Do you need a special driving licence for a forestry vehicle?
This depends on the vehicle classification, mass and country. Some countries have special agricultural or forestry vehicle licence categories, while other machines require ordinary car or heavy-vehicle licences.
Do forestry vehicles have special speed limits?
They may. The permitted speed can depend on the vehicle's construction speed, mass, road type and local traffic rules. Posted speed limits must also be respected.
Can forestry vehicles use motorways?
This depends on the country and vehicle classification. Agricultural and forestry vehicles are often restricted from high-speed roads, particularly when their construction speed is unsuitable for motorway traffic.
Why should drivers take care when passing a forestry vehicle?
Forestry vehicles can be large, slow, wide or equipped with projecting machinery. Reduce speed where necessary and overtake only when there is sufficient visibility and space.
Can a forestry vehicle tow a trailer?
Yes, where the vehicle is designed and approved to do so. Forestry tractors commonly tow trailers carrying timber, machinery or other forestry materials.
Can forestry equipment extend beyond the normal width of the vehicle?
Some machinery or loads may make a forestry vehicle unusually wide or long. Where legal limits are exceeded, special markings, lighting, permits or escort arrangements may be required under local law.

What is a construction vehicle?
A construction vehicle is a vehicle or mobile machine used for construction, excavation, lifting, roadworks or transporting construction materials.
What are examples of construction vehicles?
Examples include excavators, wheel loaders, bulldozers, road rollers, mobile cranes, dump trucks and concrete mixers.
Is every construction vehicle legally the same type of vehicle?
No. A construction vehicle may legally be classified as a truck, mobile machine, special-purpose vehicle or another vehicle category depending on its design and use.
Can construction vehicles travel on public roads?
Yes, when the vehicle is legally permitted and suitably equipped for road use. Some machines are designed mainly for construction sites and may be subject to special restrictions when travelling on public roads.
Do you need a driving licence for a construction vehicle?
This depends on the vehicle category, mass, speed and local law. Heavy trucks, mobile cranes and specialised machines may require different licence categories.
Do construction vehicles have special speed limits?
They may. A vehicle's design speed, mass, tyres, suspension and legal classification can result in a lower permitted speed than that applying to ordinary cars.
Why should you take extra care near construction vehicles?
Construction vehicles can be large, slow and difficult to manoeuvre and may have significant blind spots. They may also turn, reverse or enter a construction site unexpectedly.
What do flashing amber lights on a construction vehicle mean?
Flashing amber lights generally warn other road users that the vehicle is working, moving slowly or creating an unusual obstruction or hazard. They do not normally give the vehicle the same priority as an emergency vehicle.
Can a construction vehicle be wider or heavier than an ordinary vehicle?
Yes. Some construction machinery exceeds normal vehicle dimensions or masses. Special permits, route restrictions, warning equipment or escorts may then be required.
What should you do when passing a construction vehicle?
Reduce speed where necessary and leave sufficient space. Be aware of blind spots, projecting equipment, wide turns and workers who may be present nearby.
72. セミトレーラートラック
セミトレーラートラックは、主に貨物輸送に使われるトラクターヘッドとセミトレーラーの組み合わせです。セミトレーラーは、自身の車輪だけでなく重量のかなりの部分をトラクター側で支えるよう連結されます。

What is a semi-trailer truck?
A semi-trailer truck consists of a powered road tractor coupled to a semi-trailer primarily used to transport goods.
What is a semi-trailer?
A semi-trailer is a trailer designed so that part of the trailer and a significant part of its load are supported by the towing tractor.
What is the difference between a semi-trailer and an ordinary trailer?
An ordinary trailer generally supports its own weight through its axles, while a semi-trailer transfers a substantial vertical load to the tractor through its coupling.
How is a semi-trailer connected to the tractor?
The semi-trailer is normally connected through a kingpin and fifth-wheel coupling mounted behind the tractor cab.
Why are semi-trailer trucks called articulated vehicles?
The tractor and semi-trailer are connected by a pivoting coupling, allowing the two parts to turn relative to each other when the combination changes direction.
Do you need a special licence to drive a semi-trailer truck?
Yes. Heavy articulated trucks normally require a heavy-goods-vehicle licence that also authorises the driver to tow a heavy trailer or semi-trailer. The precise licence categories differ between countries.
Do semi-trailer trucks have lower speed limits?
They often do. Many countries impose vehicle-specific maximum speeds on heavy goods vehicles, particularly on motorways and other high-speed roads.
Why do semi-trailer trucks need more space to turn?
The semi-trailer's rear wheels follow a tighter path than the tractor's front wheels. Drivers therefore need additional space when turning, particularly at narrow intersections.
Why should you leave extra distance behind a semi-trailer truck?
Large trucks can restrict your view of traffic ahead and require considerable stopping distance. Keeping an appropriate following distance improves visibility and reaction time.
Why should you take care when driving beside a semi-trailer truck?
Large trucks have substantial blind spots around the cab and trailer. Avoid remaining beside the vehicle unnecessarily and be particularly careful when the truck is turning or changing lane.
73. トロリーバス
トロリーバスは、通常、車両に取り付けた集電装置を通じて架空電線から電力を得る電気バスです。トラムと異なり通常のゴムタイヤで道路を走行し、レールではなく運転者が操舵します。

What is a trolleybus?
A trolleybus is an electrically powered bus that normally receives electricity from overhead wires while travelling on ordinary road wheels.
Is a trolleybus the same as a tram?
No. A tram runs on rails and follows the path of its tracks. A trolleybus has ordinary tyres and is steered like a conventional bus.
Is a trolleybus an electric bus?
Yes. A trolleybus uses an electric motor, but unlike a battery-electric bus it traditionally receives most or all of its operating power from overhead electrical wires.
How does a trolleybus receive electricity?
Electrical current is normally collected from overhead wires through poles or another current-collection system mounted on the vehicle.
Can a trolleybus drive without overhead wires?
Some trolleybuses can. Modern vehicles may have batteries or auxiliary motors that allow limited operation away from the overhead wiring.
Can a trolleybus change lane?
Yes. Because it is steered rather than rail-guided, a trolleybus can move sideways within the range permitted by its overhead electrical connection and road layout.
Can trolleybuses use bus lanes?
Yes, where local rules permit. Trolleybuses operating public-transport services can normally use infrastructure reserved for authorised buses and public transport.
Do trolleybuses have priority when leaving stops?
This depends on the local traffic law. Some countries require other drivers to allow public-transport buses, including trolleybuses, to leave designated stops.
Should drivers slow down near a stopped trolleybus?
Yes. Passengers may be boarding, leaving or crossing the roadway. Drivers should approach carefully and give passengers sufficient space where required.
Does a trolleybus produce exhaust emissions?
A trolleybus operating entirely on electric power produces no combustion-engine exhaust emissions at the vehicle. Non-exhaust emissions from tyres, brakes and road wear can still occur.
74. スピードペデレック
スピードペデレックは、通常の電動アシスト自転車のアシスト上限を超えて、一般に約45 km/hまでペダルアシストを継続できる高速電動アシスト自転車です。ペダルを備え、主としてペダリングを補助する設計です。

What is a speed pedelec?
A speed pedelec is an electrically assisted pedal cycle capable of providing motor assistance at higher speeds than an ordinary electric bicycle, commonly up to approximately 45 km/h.
What is the difference between a speed pedelec and an ordinary electric bicycle?
An ordinary electrically assisted bicycle normally stops providing motor assistance at a lower speed, commonly around 25 km/h. A speed pedelec can continue assisting the rider at higher speeds.
Do you still have to pedal a speed pedelec?
Normally yes. A speed pedelec is primarily designed to provide assistance while the rider pedals, although limited walking or starting assistance may also be provided.
Can a speed pedelec travel at 45 km/h?
Many speed pedelecs are designed to provide assistance up to approximately 45 km/h. The actual permitted speed must still comply with the local speed limit and traffic conditions.
Do you need a driving licence for a speed pedelec?
This depends on the country's legal classification. Some countries classify speed pedelecs similarly to mopeds and require an appropriate driving licence.
Is a helmet compulsory on a speed pedelec?
Helmet requirements vary between countries, but because speed pedelecs travel considerably faster than ordinary bicycles, specific helmet requirements commonly apply.
Does a speed pedelec need a licence plate?
In countries where speed pedelecs are classified as mopeds or another motor-vehicle category, registration and a licence plate may be compulsory.
Does a speed pedelec need insurance?
This depends on its technical characteristics and local law. Some jurisdictions require motor-vehicle liability insurance, while others exempt pedal-assisted speed pedelecs under specified conditions.
Can a speed pedelec use a cycle path?
This depends on the country, road speed limit and traffic signs. Speed pedelecs may be permitted, required or prohibited on particular cycle paths.
Can a speed pedelec use a motorway?
Speed pedelecs are generally unsuitable for motorways and are commonly prohibited where mopeds or low-speed vehicles are not permitted. Follow the local access rules.
Can you carry a passenger on a speed pedelec?
This depends on the vehicle's construction and local rules. Where passengers are permitted, the speed pedelec must be designed and equipped to carry them safely.
Is a speed pedelec the same as an electric moped?
No. A speed pedelec is primarily designed to provide pedal assistance, while an electric moped can normally propel itself without requiring the rider to pedal. Their legal classifications may nevertheless be closely related.
75. 配送車両

What is a delivery vehicle?
A delivery vehicle is a vehicle used to transport goods, parcels, supplies or other items to a particular destination.
Is a delivery vehicle always a van or truck?
No. Deliveries can be made using vans, trucks, cars, motorcycles, cargo bicycles or other suitable vehicles.
Can a delivery vehicle stop to load or unload goods?
Yes, where stopping is legally permitted. Many traffic systems distinguish genuine loading or unloading from ordinary parking when the vehicle remains only for the time necessary to perform the activity.
Can a delivery driver wait in a loading area?
A loading area is intended for active loading or unloading. Remaining there after the delivery activity has finished may constitute parking and may therefore violate the applicable restrictions.
Can delivery vehicles use restricted streets?
Sometimes. Traffic signs may provide an exception for deliveries, loading and unloading or local access. The driver must comply with any times, vehicle restrictions or other conditions shown.
Can delivery vehicles enter pedestrian zones?
Only where local rules or signs specifically allow delivery access. Access may be limited to certain hours, and vehicles may be required to travel at very low speed and give priority to pedestrians.
Can a delivery vehicle park on a pavement or cycle path while unloading?
Not automatically. Loading or unloading does not override general stopping restrictions or rules protecting pavements, cycle paths and other road users.
Can a delivery vehicle use hazard warning lights while illegally stopped?
No. Hazard warning lights warn other road users but do not make an otherwise prohibited stopping or parking position legal.
Can delivery vehicles be restricted by low-emission zones?
Yes. Vans and trucks may be subject to low-emission-zone requirements based on factors such as fuel type, vehicle category and emission standard.
Should drivers take extra care around delivery vehicles?
Yes. Delivery vehicles may stop frequently, reverse, open doors or move between the roadway and loading areas. Other road users should allow sufficient space and anticipate pedestrians or workers moving around the vehicle.
